I do wish you luck Fenris... I go into DC about once a week and hate the fact that I can't carry - anything. I work in a federal building and cant even carry a folding pocket knife despite passing a fairly rigorous security clearance. I can't stand DC andlook forward to the day that I no longer need to go there to make a living.
Watch the kids, especially if you have to ride the red line of the metro, it's pretty rough at times with plenty of scumbags to fill the cars. It's an entirely different world.
